Spouses may have similar DNA Scientists already knew that people tend to choose romantic partners with similar characteristics, such as age, race, religion, income, and upbringings. But a study published in the Proceedings of the National Academy of Science found that people also tend to marry others with similar DNA. When researchers studied the genetic material of 825 white American couples, they found fewer differences in the DNA between married people than between two randomly selected individuals within the same race. In fact, they calculated that the tendency to pair up with a genetically similar spouse is about one-third as strong as the tendency to do so with someone with a similar education. #legit
